It's also done it a few times before, but I wasn't around and wasn't able to catch anything that it spit it before it rebooted. I was able to reproduce it, and here's what was output before the reboot: Fatal trap 12: page fault while in kernel mode fault virtual address = 0xc0f95240 fault code = supervisor read, page not present instruction pointer = 0x8:0xc018306c stack pointer = 0x10:0xc40aaba4 frame pointer = 0x10:0xc40aabc4 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 2550 (sh) interrupt mask = none trap number = 12 panic: page fault [jeremy@PLUTO:ttyp0:~]$ uname -a FreeBSD pluto.main.gaddis.org 4.8-STABLE FreeBSD 4.8-STABLE #0: Sun Jun 1 01:12:47 EST 2003 root@jupiter.main.gaddis.org:/usr/obj/usr/src/sys/PLUTO i386 [jeremy@PLUTO:ttyp0:~]$ dmesg Copyright (c) 1992-2003 The FreeBSD Project.
